SHELF-SUPPORTING BRACKET.

' Specification of Letters Patent... Application filed July 19. 1906. Serial lio- 326.822..

Patented March 5,1907.-

To all whom it may concern:

Be it known that we, JosHUA J. WORLEY and WILLIAM J. THOMAS, both citizens of the United States, and residents of Sterrett, in the county of Blue, Indian Territory, have invented certain new and useful I'mprove-' ments-in Shelf-"Supporting Brackets, of which the following is a specification.

This invention relates to shelf-supporting brackets; and it has for its object to provide a simple and improved bracket device of this class which can be quickly and readily set up in position without permanent attachment to the wall or surface with relation. to which it is mounted and. without the employment of nails or screws or other permanent securing means, which can be also quickly and readily removed from position in case of emergency or as desired, and which will be conveniently portable.

A further object of the invention is to probe set up or removed by simply the adjustable operation of the device itself andwithout the labor or expense of using permanent securing means, and which will, furthermore, possess advantages in point of convenience,

adaptability, adjustability, economy, safety,

effectiveness, and general efiiciency.

In the drawings, Figurel is a front elevatioIi illustrating the improved bracket device in use, Fig. 2 is aside elevation, partly in section, illustrating one of the improved shelf-supporting bracket devices in applied position and showing the adjustable action of the parts in dotted lines. Fig. 3 is a detail perspective view of the top end of the main member or'rack-bar of the device.

Corresponding parts in all the figuresar denoted by the same reference characters.

Referring to the drawings, 1 designates the main member of the device, which consists of a bar adapted to be placed vertically with relation to the wall or surface, as at 2, in

conjunction with which the device is mounted. Said bar 1 is provided at its bottom end with a rearwardly-Proj acting toe. or extension 3, adapted to engage under the baseboard 4 of the wall 2 or between bricks when the bar is applied to an unfinished wall, and at its top end the bar is provided with a rearwardly-projecting extension, as at 5, adapted to bear against the wall 2 and retain the rear edge of the bar a sufficient distance therefrom to enable the sliding operation of the adjustable parts hereinafter described. The top extension 5 is provided with a pointed end, as at 6, which will engage the wall 2 and prevent lateral displacement of the bar when the latter is clamped in operative position. The bar 1 is preferably curved or extended rearwardly, as at 7, a short distance above the toe or extension 3 to form a short projecting portion, the rear edge of which will bear-against the wall 2 immediately above the baseboard 4 to retain, in conjunction with the top extension 5, the main upper length of the bar a sufficient distance from the wall to enable the operation of the sliding and adjustable parts as above mentioned. The front edge of the bar 1 is provided throughout its length above the curved or rearwardly-projecting portion. 7 with serrations, as at 8, forming a rack.

9 designatesthe adjustable shelf-supporting members of the device, which comprise a body portion, as at 10, carried upon a sleeve or collar 11, which latter embraces and is vertically slidable upon the rack-bar 1. The body portion 10 of the member 9 comprises a normallyv horizontal top-supporting surface 12 and a serrated edge 14, which is normally vertical and at right angles to the top surface 12 and which has a locking engagement with the serrated front edge 8 of the rack-bar 1, and the body portion 10 is pivotally connected to its carrying sleeve or collar 11 at the vertex ofthe angle formed by its top surface 12 and edge 14, as shown at 15. The relative 1 construction and arrangement just described results in a locked position of the member 9 at any point to which it has been adjusted, downward pressure upon the body portion 10 of said'meinber 9,. caused by weight upon the shelves, only serving to more firmly lock the member in position; but for purposes of adjustment the body portion may be turned upon its pivot to the position shown in dotted lines in Fig. 2 to enable the slidable v adjustment or placing of the member 9 at any desired point upon the rack-bar 1.

16 designates a cam-brace device by WhlGh ICC .collar 17 carries a pivoted gravity-cam 20,

and portable shelf-supporting device need the rack-bar 1 may be firmly secured and i bound in upright positionin engagement with the wall 2. This cam-brace comprises a sleeve or collar 17, embracing and slidable upon the rack-b ar 1 above its bearing extension portion 7 and pivotally carryin as at i 18, at its outer end a lever 19. The s eeve or projecting rearwardly toward the rack edge 8 of the bar 1 and having a segmental serrated edge, as at 21, adapted to engage and lock with the serrations 8. The cam20 is preferablymounted at the pivot 18, which con nects the lever 19 and the sleeve'17. The lever 19 carries a pivoted fulcrum-bar 22, which preferably has a pointed lower end 23, adapted to engage the floor 24, the pivot, as at 25, of the fulcrum-bar being at a point intermediate the ends of the. lever. The lever 19 is preferably of skeleton construction, comprising two side plates 26 26, between which the fulcrum-bar 22 is received when the cam-brace device 16'is in normal position, and at the lower end of the lever said plates are preferably connected at the outer side ofthe lever by a crosspiece 27, which will limit the position of the fulcrum-bar 22 when the brace is in normal position and preyent accidental-displacement of the fulcrum- It will be understood that when the rackbar'l hasbeen placed in position with the cam 20 en aging the serrated edge 8 and the lever 19 fu crumed upon the fulcrum-bar 22, with the latter in approximately upright position and engaging the floor 24, (this initial position being illustrated in dotted lines in Fig. 2,) by bearing downwardly upon the outer or power end ofthe lever the rack-bar 1 will be forced into position, engagin the wall 2 and under the base-board 4, as ereinbefore described, and when the cam-brace device is brought to the normal position shown in Figs. 1 and 2 it will-operate to firmly retain the rack-bar in upright position.

It will be noted that the 'memberi16 when in normal position need project no farther or but little farther than the degree of projection of the shelves 28, whereby compactness m space occupied is secured, and our improved adjustable, attachable, detachable,

occupy no greater space than that required for ordinary permanent shelving which is built up and fixed to the wall in permanent attachment by nails or screws or other permanent securing means.

The shelves 28 are supported upon the top surface 12 of the members 9 in number and arrangement as desired, and if it is required that the shelves be secured to the members 9 this may be done by screws,'as at 29, or other suitable securing means, for which purpose the top portion 12 of the members 9 may be provided with openings, as at3( The operation and advantages of our invention will'be readily understood.

Any desired number of main members or rack-bars 1 and any desired number of shelfsupporting members 9 may be employed, ac-

cording to thelength of the shelvin and the number of shelves desired. After t e members 1, 9, and 16 are mounted in normal position, as shown in Figs. 1 and 2, and the shelving applied the-entire'device will firmly and securely retain its normal operative posi- 1 1.
